What Does a Blinking Yellow Light Mean?
The word flashing does not make red and yellow indications equivalent. This California exercise concerns a flashing circular yellow light: slow down and proceed cautiously. It is a warning to evaluate the actual intersection, not a guarantee of priority and not an instruction to accelerate. Distinguish the color, whether it is flashing and whether the indication is circular or an arrow. That careful reading prevents a remembered phrase about another signal from answering the wrong question. A caution message requires an observation and a controlled response. Source
The short answer

Why this answer fits the situation
Proceeding cautiously does not mean holding an unchanged speed without looking; it means accounting for the people and traffic in your path. The handbook distinguishes this warning from the stop required for flashing red. It also differs from a steady yellow change indication. The original question does not ask you to predict the next color or to apply a special turn-arrow rule to a circular signal.
How to read the decision on the road
First name the indication you are actually facing. Then identify the intended movement and look for conflicts rather than treating a flashing light as a general invitation to enter. Do not infer that another driver has understood the same arrangement. In the mini-quiz, the correct answer combines a speed adjustment with caution. The alternatives either invent a waiting requirement, encourage the opposite of caution or reduce the assessment to one arbitrary direction.
Why the other choices do not fit
Wait until it turns green
Waiting until the light changes imports a stopping-and-waiting rule not stated by this flashing-yellow indication. Stop when the actual traffic situation requires it, but do not confuse the signal itself with the distinct flashing-red instruction.
Speed up to clear it
Accelerating through conflicts with a caution warning. The light does not announce that crossing traffic has vanished, and gaining speed does not provide the observation or room to respond that the actual situation may require.
Give way only to cars from the right
Looking or yielding only to the right ignores other possible conflicts. The warning does not identify a single side as the only place from which a pedestrian, turning vehicle or other road user could affect your movement.
